Background: Anti-gliadin antibodies (AGA) occur in approximately 10% of the general population, produced as a response to gluten. Autoimmune gluten-related disorders can have detrimental neurological effects if not properly controlled but the relevance of such "incidental" AGA is not properly established; any harm caused would indicate the gluten-free diet as a means for affected people to protect their brain health. We explored this question by comparing brain MRI scanning, cognitive testing and other measures between healthy volunteers with and without AGA.

We present the largest study comparing adherence to a GFD in patients with Coeliac Disease (CD) and NCGWS and assess its impact on quality of life (QoL) and sleep in patients with NCGWS.
Methods: Patients with NCGWS at a tertiary centre completed the Coeliac Disease Adherence Test (CDAT), Coeliac Symptom Index (CSI) and Sleep Condition Indicator (SCI).
We have previously shown that 67% of patients with newly diagnosed coeliac disease (CD) presenting to gastroenterologists have evidence of neurological dysfunction. This manifested with headache and loss of co-ordination. Furthermore 60% of these patients had abnormal brain imaging.

While a number of specialist diets have been suggested as beneficial in ASD, gluten has received particularly close attention as a potentially exacerbating factor. Reports exist suggesting a beneficial effect of the gluten-free diet (GFD) in ameliorating behavioural and intellectual problems associated with ASD, while epidemiological research has also shown a comorbidity between ASD and coeliac disease.

We initially conducted a prospective postal survey to investigate its neurological presentation and symptom course. Results from this then motivated a follow-up pilot study utilising brain MRI to characterise potential diagnostic biomarkers for future research.

Healthy controls ( = 21), newly diagnosed CD patients (NCD; = 19) and established CD patients (ECD; = 35) were recruited from a specialist UK centre. Participants underwent a cognitive test battery that established seven overall domain scores.

To validate previous reports, we investigated the prevalence of neuropsychological dysfunction in persons with celiac disease included in the National UK Biobank, which contains experimental medical data from 500,000 adults in the United Kingdom.
Methods: Biobank participants with celiac disease (n = 104; mean age, 63 years; 65% female) were matched with healthy individuals (controls, n = 198; mean age, 63 years; 67% female) for age, sex, level of education, body mass index, and diagnosis of hypertension.
It is unclear how the prevalence of people who believe the gluten-free diet (GFD) to be generally healthy ("Lifestylers") is impacting the overall rates of self-reported gluten sensitivity (GS). We repeated a population survey from 2012 in order to examine how attitudes towards GS have changed over time. Our survey ( = 1004) was administered in Sheffield (UK) in 2015, replicating the 2012 experiment.

We evaluated the presence of neurologic deficits and investigated whether the presence of antibodies to Transglutaminase 6 (TG6) increases the risk of neurologic defects in patients with a new diagnosis of celiac disease.
Methods: We performed a prospective cohort study at a secondary-care gastroenterology center of 100 consecutive patients who received a new diagnosis of celiac disease based on gastroscopy and duodenal biopsy.
Objective: To identify novel genetic associations with white matter hyperintensities (WMH).
Methods: We performed a genome-wide association meta-analysis of WMH volumes in 11,226 individuals, including 8,429 population-based individuals from UK Biobank and 2,797 stroke patients. Replication of novel loci was performed in an independent dataset of 1,202 individuals.
Importance: Blood pressure (BP) lowering is considered neuroprotective in patients with cerebral small vessel disease; however, more intensive regimens may increase cerebral hypoperfusion. This study examined the effect of standard vs intensive BP treatment on cerebral perfusion in patients with severe small vessel disease.
Objective: To investigate whether standard vs intensive BP lowering over 3 months causes decreased cerebral perfusion in small vessel disease.
Diffusion tensor imaging (DTI) metrics such as fractional anisotropy (FA) and mean diffusivity (MD) have been proposed as clinical trial markers of cerebral small vessel disease (SVD) due to their associations with outcomes such as cognition. However, studies investigating this have been predominantly single-centre. As clinical trials are likely to be multisite, further studies are required to determine whether associations with cognition of similar strengths can be detected in a multicentre setting.

Observable metabolites reflect neuronal density and viability, glial density, membrane injury, and hypoxia or ischemia. MRS has been used in traumatic brain injury (TBI) research for nearly 20 years and this article reviews the MRS findings in the adult TBI population.

Methods: Fifty-three patients were scanned an average of 6 days postinjury (range = 1-14 days). Twenty-three patients were rescanned 1 year later.
